No. 509,743 6 Claims. (Cl. 5-360) This invention relates to insulator pads and particularly to insulator pads for seat and cushion construction.

In the manufacture of mattresses, seats and the like, it is conventional to provide a pad, known as an insulator pad, in overlying relation to the springs in order to prevent the padding from moving downwardly within and between the springs and thereby more evenly distribute the load onto the springs.

It is an object of this invention to provide an improved insulator pad.

It is a further object of the invention to provide an improved mattress having an insulator pad.

It is a further lobject of the invention to provide an improved seat construction with an insulator pad.

In the drawings:

FIG. 1 is a fragmentary vertical sectional view through a mattress embodying the invention. v

FIG. 2 is a fragmentary vertical sectional view through a seat cushion embodying the invention.

FIG. 3 is a sectional view taken along the line 3 3 in FIG. 5.

FIG. 4 is a fragmentary perspective view of an insulator pad embodying the invention.

FIG. 5 is a plan view of a seat embodying the invention.

FIG. 6 is a plan view of still another form of seat embodying the invention.

Referring to FIG. 4, the insulator pad embodying the invention comprises a sheet of flexible open mesh or solid material 10 such as burlap, tobacco cloth, resinated cotton, cotton or liber, paper, plastic, paper by-products, sisal and the like. A plurality of parallel metal wires or strands 11 are interwoven through the sheet 10. Ends 13 of the strands 11 are turned over flexible cords 12 of paper or the like to interconnect the strands 11 and cords 12. A portion 14 of the sheet 1i) extends beyond one of the cords 12 and is folded over an edge pad 15 of cotton or the like and sewed to itself and the edge pad 15 along the line 16. A portion 17 of the sheet 10 extends beyond the edge pad 15. Another portion 1S extends beyond the other cord 12.

The insulator pad shown in FIG. 4 can be utilized in connection with mattresses and seats in various manners. For example as shown in FIG. 1, a conventional mattress spring construction comprises a plurality of coil springs interconnected by wires including border wires 21. An insulator pad made in -accordance with the invention is placed in overlying relation to the -coil springs 26 with r the portion 14 projecting downwardly from the edge of the endmost springs 20 so that the edge pad 15 extends vertically. The projecting portion 17 is drawn taut and connected to the bottom of the mattress by hog rings 18.

In the form of the invention shown in FIG. 2, the insulator pad 10 is similarly positioned on a seat frame 21 which has sinuous springs 22 extending transversely to the Wires or strands. The extending portion 17 is drawn taut and fastened to the frame by staples 23. Extending portion 18 adjacent and beyond the other cord 12 is drawn taut and fastened to the frame by staples 24.

In the form of the invention shown in FIGS. 3 and 5, the seat 25 comprises a frame 26 that has a plurality of sinuous wires 27 extending transversely between the sides of the frame 21. The insulator pad is positioned over the wires with the strands 11 at right angles to the sinuous springs 27. In this form of the invention, the edge pad 15 lies on an inclined surface 28 of the frame. The extending portion 17 is drawn taut and fastened by staples 29 and the extending portion 18 is drawn taut and fastened by staples 30 to the underside of the seat frame 26.

FIG. 5 is a plan view of the seat shown in FIG. 3 and it can be seen that the pad 14 extends in overlying relatioiship to the inclined surface 28 to serve as a protective pa In the form of the invention shown in FIG. 6, the frame 31 of the 4seat is similar in constru-ction to that shown in FIGS. 3 and 5 except that the sinuous wires 32 extend between the front and rear portions of the frame rather than transversely between the sides. In this form, the edge pad 15 is provided adjacent the outermost wire 11 of the insulator pad so that it will overlie the surface 28.

It can thus be seen that the insulator pad can be provided either adjacent one of the cords 12 or adjacent one of the outermost Wires 11. In each case, the flexible sheet 10 projects outwardly beyond the area of juncture of the pad to the sheet.

I claim:

1. An insulator pad comprising a sheet of flexible material,

a plurality of parallel strands interwoven through said flexible material, flexible cords extending transversely of said strands and connected to and joining the ends of said strands,

said sheet having a portion extending outwardly beyond the confines of the strands and cords in a direction beyond one periphery thereof,

an edge pad,

and means for fastening said edge pad to said portion of said sheet which extends beyond the connes of said strands and cords in such a manner that said edge pad extends parallel to one of said strands and said cords,

said sheet of flexible material being folded over said edge pad and fastened to itself and to said edge pad.

2. An insulator pad comprising a sheet of flexible open mesh material,

a plurality of parallel strands interwoven through said sheet, flexible cords extending transversely of said strands and connected to and joining the ends of said strands,

said sheet having a portion extending beyond the confines of the strands and cords in a direction beyond one periphery thereof,

an edge pad,

and means for fastening said edge pad to said portion of said sheet which extends beyond the confines of said strands and said cords in such a manner that said edge pad extends parallel to one of said strands and said cords,

said means for fastening said edge pad to said sheet comprising said extending portion of said sheet of flexible material folded over said edge pad and fastened to itself and to said pad.

3. The combination comprising a spring structure,

an insulator pad overlying said spring structure and comprising a sheet of llexible material,

a plurality of parallel strands interwoven through said lflexible material,

cords extending transversely of said strands and connected to and joining the ends of said strands,
